lMPROVEMENT l N'CORN-PL.'ANTERS.

Specification forming part of Letters Patent No. 25,613, dated October 4, 1859.

Indiana, have invented a new and useful Im provement in Corn-Planters; and I do hereby declare that the following is a full and clear 7 description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon and made to form a part of this specification.

The nature of the invention relates to the means used for controlling the depth of the plows in the ground.

In reference to the accompanying drawings, Figure 1 is a perspective view, showing the planter with all its working parts arranged for operation. Fig. 2 is aside elevation of the planter.

A A represent the frames of the planter, arranged upon two wheels, 13, the part A of the frame being permanently attached to the axletree 0, and the parts A or plow-frames being hinged to the frame A at d.

Attachedto the plowframes A, and pivoted together at e, are plates 0, which extend forward to and are fitted upon the ends of the axle-tree c, by means of which an even draft is given to the plow-frames and their plows, and at the same time they are allowed a vertical motion,which adapts the plows to any inequality in the surface of the ground, or allows the said frames A to be elevated, so as to free the said plows from the ground when required.

Firmly secured to the frame. A at j, provided with braces g, and arranged to pass through mortises g of the frames A are semicircular supports 9, having in them perforations 71, and pivoted to the frames A at k are springs 2', provided with pins i, which are adapted to the perforations h of the supports so that by raising the frames A and inserting the pins t" in the supports g below said frames A said frames A,'together with their plows f f,will be sustained entirely free from the ground, as shown clearly by the red lines in Fig. 2, and by inserting said pins 13, as aforesaid, above the frames A, the plows f f may be confined to their proper depth in the ground, or allowed any desired degree of vertical motion.

f are furrowing-plows, secured upon the cross-bars Z of the frames A in such manner as to be allowed vertical adjustment with ret erence to said bar I.

f are eox'ering-plows firmly secured to the longitudinal timbers of the frames A, as clearly shown in Fig. 1.

m is the droppers seat, attached to the spring-bars 'n Said spring-bars a are pivoted to the frame A at a, and arranged in such manner as to rest upon the axle-tree 0, so that the weight of the dropper bears upon the axletree, and at the same time the spring of the bars it affords to the said dropper an easy and comfortable seat. i

p is a seat for the driver.

9' is an adjustable bar through which the pole .9 passes.

t is a notched clevis, by means of which the after end of the pole is secured to the axletree; and by means of the adjustable bar 1', in combination with the clevis T, the pole 8 may beso arranged and adjusted as to facilitate the operation of the plows f f with. reference to their proper depth in the ground, and also with reference to the balancing of the weight of the operators and frame A upon the axletree 0. V

o are hoppers or conductors through which the corn may be deposited upon the ground.

The operation of the planter may be described follows: The dropper will sit upon the seat 121, with a vessel containing the corn to be planted secured in front of his person in a convenient manner for use. The plows f f will'be adjusted, as before described, to a proper depth in the ground. The planter will then be moved forward, and the dropper will drop the corn with both hands at the same time at the proper places of deposit. The

ground may be eross-furrowed before planting by means of the plows f, so that the corn may be planted in cheek-rows, if desired.

Having fully described the construction an d operation of my invention, what I claim as my vice being made so as to clasp together crossinvention, and desire to secure by Letters 'Patpieces 0 and c, all in the manner and for the ent, ispurpose set forth.

ADAMS. when the said bar is made adjustable by \Vitnesses: means of bolts and bolt-holes through its ends, H. E. CLIFTON, and through the frame-pieces A, said clevis de- 1 F. A. MCDOWELL.
